(a) compute the mean and sample standard deviation in each condition (b) changing conditions A,B,C changes dependent scores from around 11.00 to 32.75 to 48.00 respectively (c) the S x for the three conditions are .71, 1.09, and .71, respectively. These seem small, showing little spread, so participants scored consistently in each condition. 23. (a) Study A has a relatively narrow/skinny distribution; Study B has a wide/fat distribution. (b) In A, about 68% of the scores will be between 35(40 5) and 45(40 + 5); in B, 68% will be between 30(40 10) and 50(40 + 10) 25. (a) for conditions 1,2 ,and 3 we would expect s of about 13.33, 8.33, and 5.67, respectively (b) somewhat inconsistently, because based on s x wed expect a x of 4.51, 2.52,and 3.06, respectively....
